Latch immune CMOS technology enables ruggedized monolithic construction. The output driver features a high pulse current buffer stage designed for minimum cross-conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage. Cycle-by-cycle shutdown is programmed by ir21121 external capacitor which directly controls the time interval between detection of the over-current limiting condition and latched shutdown.
All voltage parameters are absolute voltages referenced to COM.
